Hi,
I'm trying to capture the data on a ATA/ATAPI interface using a digital discovery. Repeat mode and shift mode seem to work ok, but record mode is just a bit, sketchy. Sometimes it triggers, sometimes it doesn't. Sometimes it makes the led on the digital discovery turn white (what does that even mean).
Despite me setting the granularity of the sampling, it seems to do its own thing, so that once my capture is over and i try and zoom in on the black blob it produces (i need to read pulses of 80ns) , despite being say 5 seconds into the capture, the time is set as -445ns, what?
If i manage to find the event in the data pane, double clicking the row does nothing, but right click and select centre, takes me to the event, sort of.
This feels very much like all the love is being given to analogue discovery, i'm getting buyers remorse. Please tell me its me and that i'm suffering from PEBCAK.
On a slightly different note, i set 8 data lines up as a bus, hoping for some decode, but it cant handle the fact that the lines might be active low, which is a bit of an oversight. So how can i script a decode in javascript i cant find any exmples for decoding using the digital discovery.
Cheers,
